A sample example for uploading files using ftp in python

ftp_uploader.py

#!/usr/bin/python
import ftplib
session = ftplib.FTP('example.com','username','password')
file = open('cup.mp4','rb')                  # file to send
session.storbinary('STOR '+'cup.mp4', file)     # send the file
file.close()                                    # close file and FTP
session.quit()

what if the file i want to upload it not in the same path?
how can i specified another file with different path which the end user is want?
